TUBULAR LANTERN OR LAMP.

SPECIFICATION forming part of Letters Patent No. 389,832, datedSeptember 18, 1888. Application filed March 7, 1888. Serial No. 266,391.(No model.)

To all whom it may concern:

Be it known that I, LEWIS F. BETTS, of New York city,county and State ofNew York, have invented certain new and useful Improvements in TubularLanterns or Lamps, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

- My invention relates to tubular lanterns or tubular lamps, and has forits object the production or provision of a simple,cheap,eflective, andeasily-constructed guard or protector for the removable globe, involvingcertain pe- 1 culiarities of construction and operation, as will behereinafter first fully explained, and then pointed out in the claims. 7

In the accompanying drawings, forming part of this specification, Figure1 is an elevation of a tubular lantern having my improved guard appliedthereon or in connection therewith. Fig. 2 is a horizontal section andplan view upon a plane through line :0 m of Fig. 1. Fig. 3 is a plan ofthe perforated bottom plate detached from the globe, the flange or rimthereof being shown as extended and slotted to permit the application orlocation of the guard-wire. Fig. 4 is aplan ofthe bottom plate,showingthe guard-wire attached o thereto and ready to be afterward bent up inproper shape to form the guard. Fig. 5 is a view in elevation showingthe guard and perforated bottom plate, the former being bent to finalposition and the whole ready for use in the lantern.

In all these figures like letters of reference, wherever they occur,indicate corresponding parts.

A is the glass globe or flame protector,

which rests upon a perforated bottom plate,B.

O O are side tubes which conduct air down to the under side of theburner-cone, as in tubular lantern or lamp structures generally. Drepresents the dome; E, the oilpot, and F 5 the base-piece or rimthereof.

In the example shown the globe, the perforated bottom plate thereof, andthe dome are made vertically adjustable to uncover the burner-cone, thelift-wires a a,connected with the perforated bottom plate, being guidedin suitable loops, 1) b, secured to the air tubes. The air-tubes afforda guard or protection for the globe at points on opposite sides. Theguard-wire is intended to protect the spaces or parts between the tubesand not protected by the tubes.

1 supply the bottom plate, B, with a rim or flange, c, of widthsufficient to turn upon and hold the guard-wire, and this rim Iperforate or slot or notch at opposite points, as at d d,

'where the hinge-loops e e project, and also as at f f and g y, wherethe longer portions h h of the guard-wire project. The guard-wire e e hh is intended to be continuous, though of course it may be made of partsor pieces properly joined. This wire, being bent to about the form shownin Fig. 4., is secured (while flat) to the rim or flange c by bendingthe latter, and afterward may be further secured by solder,'if desired.Being thus secured the guard is afterward bent up to final position, (inany suitable press or by any suitable tool,) as in Fig. 5, and is thenready for use. The guard is thus easily and quickly made and answers allother desired purposes. The loops e receive the lower ends of theliftwires a, by which the bottom plate is elevated, and they permit theturning or tilting of the bottom plate to facilitate withdrawal of theglobe from or insertion between the two parts of the guard. Thisconstruction constitutes a hingeconnection between the liftwires andbottom plate. A similar form of guard may be applied without the loops 2c,

as when the lift-wires are not employed; but 8 the guard-wire should becontinuous (or practically so) and capable of being secured and bent upafter themanner above explained.

I make no claim herein to the mere attachment of independent guard-wiresto the bot- 0 tom plate; but

What I do claim as new, and desire to secure by Letters Patent, isv r 1.In combination with the perforated bottom plate of a tubular lantern orlamp, a con- 5 tinuous guard-wire applied in the notched or recessedflange secured thereon and having the oppositely-projecting portionsbent up to constitute the guard, substantially as shown and described.

2. In combination with the perforated bot- In testimony that I claim theforegoing I tom plate of a tubularlantern or lamp and the have hereuntoset my hand in the presence of [o lift-wires, a continuous guard-wireapplied in two witnesses. the notched or recessed flange of the bottom 71 5 plate,the said Wire affording the main loops for IS BETTS' theguard, and the hinge-loops for engagement \Vitnesses: with thelift-wires, substantially as shown and I.
